looking for apartment (Rio de Janeiro)

I amlooking for a short term period apartment (3 months) for 2 young professionals (architects, need 2 rooms) in Barra de Tijuca. The starting date would be the Protected content June. Budget is Protected content for the 2 of us. Another option would be 2 separate rooms in different places sharing with other people.

By the way does anyone know what are the best options to look for apartments in Barra? Any web pages?
